Fig. 9. is a detail view of a portion of ring ha may be die cast or'otherwise constructed without a joint.

The preferred form of the improved spacby Figs. 1 and 2, consists, of a plurality of";

projections 7 cutfrom and struck outwardly from each saw 8, the supporting or holding means 7 being bent at a slight angle to the one face of each saw, as shown by Fig. 1. The free ends of the supporting or holding means 7 are at such distance from the shaft 6 onwhich the saws 8 are mounted that the. rings=5 will have their inner surfaces in engagement with said ends of the projectionsand be held 1n concentr1c relation to the shaft 6, as shown by Fig. 2. The end collar 9 of the saw cylinder is secured to the V shaft 6 through a screwthreaded connece r of making the rings endless" may be adopted as may be preferred. As indicated by Fig.-

tion, as at 10, and is provided with an inwardly projected flange 11 which also engages or bearsupon the projections 7 of the adjacent saw 8, as shown by Fig. 1. The

spacing device or ring 5 is of suchrdiameter that a comparatively small portion of each saw between thering spacer and periphery of the saw remains to be hammered, it. being. unnecessary to hammer or otherw1se treat the portion ofthe saw between the.

inner surface of each ring and the shaft 6 on -which the sawls mounted. It will also be seen that when the saws 8 are all grouped on the shaft 6, or the saw cylinder com 'pleted, a compact structure results from the interposition ofthe ringspacers 5 between the saws 8 and that the spaces between-the saws are materially closed by the rings and are also given arigid-support or resistance against bendmg and W111 as a consequence be maintained. in true running position or centrally with relation to thespaces between the gin ribs. The ringspacers 5 are made of suitable metal and the ends thereof may be connected in a number of ways, such'for instance as shown by Figs. 6', 7 and 8, In the form of joint shown by Figs. 6 and 8, the two ends of the ring spacer are lapped, as at 12, and are spot-welded or riveted;

-or as shown by Fig. 7 the two ends may be butt-welded, as at 13, or any other mode 9, the ringspacer may be formed continuous without "joint, or be a' die cast 'ring.

' In the form ofthe' improvement as shown by Figs. 3 and4, the saws '8 areeach'formed with a plurality of openings 1% around the center, and in the said openings the reduced ends 15 of cylindrical pins 16 are inserted,

said pins being of such length as to extend from one saw to another and to maintain the saws in proper spaced relation. The ring spacer 5 its over and is supported by the pins 16, as clearly shown by Fig. 4:, the

openings 14 and the pins 16 in engagement ring spacers 5 will be uniformly held in concentricIrelation 'to the' shaft .6 upon which the saws 8 are mounted.

As shown by Fig. 5 a furthermodification, is illustrated and consists-in forming a fiat pin or supporting means 17 having reduced ends 18 toengage correspondingly shapedopenings 19formed in the saws 8 and operating in the same manner as the cylindrical pins 16 shown by Figs. 3' and 4;

F romthe foregoingit will'beseen that the supporting means for the rings may be either an integral part of the saws or separate partsengaging the saws, the object being'to provide a ring spacer supporting means to hold the rings in concentric relation to the shaft of thefsaw cylinder for the purpose of rendering the saws of a gin saw cylinderinore effective in performing their ginning operations relatively-to seed cotton disposed in aroll box" of a gin or in linters to remove the lint fromthe seeds or for any other purpose where sawsarranged in cylindrical form'are adaptedto be used in a grouped organization. The main advantage of the improved ring spacer is that it may be constructed at a materially reduced. expense'relatively to similar devices heretofore used, particularlyin view of the fact that there is no web extending between the same and theshaft of the saw cylinder, and for the further reason that the surface of the ring spacer is smooth and free of indentations, corrugations or other formations that have been heretofore adopted. By utilizing a part of each saw as a supporting means for the ring spacer as shown in the preferred form illustrated by Figs. 1 and 2, the cost of organi'zationis also materially reduced and the strength and durability of the saws are not in the least impaired. The supporting means or projections are located at points sufficiently inwardly from the peripheries of the saws to avoid the least interference with thepractical operation of the toothed edges orp'arts of thesaws projecting outwardly beyond the ring spacers and which mo'vebetween the ribsof'the gins orli'nt'ers, and this inwardlocation of the supporting means or p'rojections'for engaging the ring spacers obviates any weakening of the saws, particularly in View of the reinforcing efiect of the ring spacers which are located eXteriorly of the said supporting means or projections.

What is claimed is: c

l. Gin saws having carrying means rotatable therewith and supporting means solely held thereby, combined with ring spacers between the saws and engaging the said saws around the supporting means and located outwardly and free of engaging relation to the carrying means, and also located at a considerable distance inwardly from the bases of the teeth of the saws.

2. Gin saws and supporting means held thereby, a shaft on which the saws are directly mounted, the supporting means being at a distance outwardly from the points of mounting of the saws on the shaft and held solely by and between the saws, and ring spacers having opposite edges engaging the saws and surrounding and bearing upon the supporting means in concentric relation to and free of the shaft and at a considerable distance inwardly from the bases of the saw teeth.

3. Gin saws having a shaft with which inner portions thereof directly engage and supporting means held solely by and between the saws, said supporting means having a bearing exposure at points between the inner shaft engaging portions and teeth of the saws, and band ring spacers surrounding and engaging the outer portions of the supporting means in concentric relation to the shaft and inclosing the spaces between the saws at a considerable distance inwardly from the teeth of the saws to the said shaft.

4:. Gin saws, a shaft with which the saws directly engage, and ring spacersinterposed between the saws and having opposite edge portions thereof directly bearing upon the side portions of adjacent saws and closing the spaces between the saws from the points of location of the spacers inwardly to the shaft, the ring spacers being held solely by the saws and clear of engagement with relation to the shaft, the ring spacers being maintained in fixed applied positions solely by means held by the saws and providing bearings between the latter for the spacers.

5. Gin saws, a shaft with which the saws directly engage, ring spacers interposed between and having opposite side edges engaging the adjacent sides of the saws and fully closing the spaces between the saws, the ring spacers being free of contact with any part of the shaft and having clear spaces between the same and the shaft and also provided with outer smooth surfaces of an unbroken character, the ring spacers being maintained in positions against inward and outward 'movement relatively to the shaft by means held solely by and between the saws and located between the latter.

6. Gin saws having supporting means struck outwardly from intermediate portions of the body thereof, combined with ring spacers between the saws and surrounding and engaging the said supporting means.

G111 saws having supporting means struck outwardly from intermediate portions of the body and disposed at an angle to one side thereof, and ring spacers surrounding and engaging the said supporting means and held in concentric relation to the saws. I

8. Gin saws having portions thereof struck outwardly at an angle therefrom to provide exposed bearing projections at intervals around the centers of the saws, a

shaft on which the saws are mounted, and

ring spacers between the saws surrounding the bearing projections out of contact with relation to the shaft, the said spacers having their opposite side edges in engagement with adjacent saws.

In testimony whereof I have. hereunto set my hand in presence of two subscribing wit nesses.
